SVG Optimizations and Router Improvements

Use svgo to optimize the crap out of the svg templates and created output (small files are happy files). Base the rest of the file creation off of this optimized svg file. This change to the templates may impact the ability to edit the files manually in inkscape, but it doesn't seem like a requirement.

The router config was improved to allow it to generate URLs for the app (so it can be hosted in a location that isn't the server root).

And some composer autoloader fluff.
